Definitions

  • the present invention relates to the locking of actuators specifically in one of a speed input unit for an automatic transmission in vehicles. More particularly, the invention relates to a manual speed input unit having a plurality of actuators, such as a selector lever and a push button.
  • Shift-by-wire circuits have the fundamental problem that in gearbox failure or in the event of failure of the vehicle electronics (failure of the transmission control unit, failure of the circuit electronics, line interruption, Failure of the power supply, etc.) the transmission can no longer execute the commands of the driver or the transmission can no longer be configured.
  • a guaranteed not overlooked feedback represents the locking or setting of the corresponding actuator.
  • the driver immediately recognizes that the desired transmission setting can not be executed or implemented.
  • the object of the present invention is therefore to provide a multi-component manual input unit with regard to the operating elements a simultaneous blocking of all components under certain conditions can be performed.
  • a manual speed input unit for selecting speed levels with a first actuating element for selecting at least one driving stage and at least one further actuating element for setting additional functions.
  • a pawl which can be moved by means of an actuator is provided, by means of which the first and the at least one further actuating element can be locked and unlocked at the same time.
  • the speed input unit according to the invention is designed such that differ in their operation at least two actuators.
  • the first actuating element can represent a selector lever and the second actuating element a button.
  • the pawl is inventively arranged so that in a first position of the pawl all actuators are locked and therefore can not be operated and in a second position of the pawl all actuators are unlocked and can be operated.
  • the first position by mechanical spring force and the second position occupied by electrical activation of the actuator are advantageousously, the first position by mechanical spring force and the second position occupied by electrical activation of the actuator.
  • the selector lever is a monostable selector lever, which returns to its original position after manual deflection in at least one direction.
  • the button returns to its original position after its operation.
  • the actuator is preferably an electromagnet.
  • the speed input unit comprises a plurality of actuators, wherein by a corresponding arrangement relative to the pawl, a first part of these actuators locked and at the same time the other part can be unlocked.
  • FIG. 1 shows a perspective view obliquely from above on an embodiment of a manual speed input unit 1 according to the invention.
  • the speed input unit 1 has two actuating elements in the form of a selector lever 2 and a pushbutton 3.
  • the lower end of the selector lever (snap-10) is pressed by a built-in lower part of the lever shaft compression spring 9 against a wedge-shaped latching contour 11, so that after a deflection of the selector lever to the selector lever pivot point 12 again the original middle Position of the lever is taken.
  • This behavior of the selector lever 2 is called monostable Behavior referred to as the selector lever always occupies a preferred middle position.
  • the driving position P (PARK), the driver according to the embodiment of Figure 1, regardless of the selector lever adjustment by pressing the button 3 select. After pressing the button 3, this also returns to its original position.
  • the inventive manual gear input unit of the above embodiment is shown from the side.
  • the selector lever 2 is in the undeflected state, the button 3 is not activated.
  • the shaft of the button 3 has a protuberance 15 in the amount of a sensor 5.
  • the sensor 5 has a contact lever on which in the non-activated state ( Figure 1) of the button 3 is opened.
  • the protuberance 15 closes the contact lever of the sensor 5 (FIG. 2).
  • the contact closure causes the corresponding electrical command to the transmission in this case to take the P (PARK).
  • a pawl 6 is provided which is pivotally mounted at one end 7.
  • the pawl 6 takes an engagement of the pawl 6 in the two actuators (selector lever 2 and button 3) so that a locking of these actuators 2.3 takes place.
  • the engagement is realized by recesses of the pawl 6 at the level of the probe shaft and the undeflected selector shaft.
  • the shaft of the respective actuating element may have a recess into which the pawl is pivoted.
  • the pivoting of the pawl 6 is effected on the one hand by an actuator 8 (e.g., an electromagnet) on the other hand by a return spring. It makes sense, therefore, the pawl 6 monostable and indeed in such a way that in the de-energized state of the manual speed input unit 1, the return spring causes a mutual engagement of the pawl 6 with the actuators 2.3 and thus a lock.
  • the releasing position of the pawl 6 is preferably given by the energized position of the actuator 8, so that in case of failure of the power supply (power supply) solely by the purely mechanical restoring force of the return spring, the actuators are locked 2.3.
  • the pawl 6 is arranged in the figure 4 so that the recesses 14 the Shaft of the respective actuating element comprise, so that on the one hand, the selector lever 2 is no longer deflected from its initial position and on the other hand, the button 3 can not be pressed.
  • Figure 4 describes the situation in case of elimination of the electrical power supply, in which by the bias of a return spring, the engagement of the pawl is effected in the actuators and their blocking. A tilting or tapping the selector lever 2 and a depression of the button 3 is no longer possible in this state, whereby the driver is made aware that the control of the transmission and thus a speed step selection is no longer possible.
  • FIG. 5 shows the situation with existing electrical energy.
  • the pawl is deflected against the force of the return spring and the shafts of both actuators released, so that a tilting or tapping of the selector lever 2 and a push of the button 3 is possible.
  • Both actuators 2, 3 are activated, i. the selector lever 2 can be tilted and the button 3 can be pressed, the protuberance 15 closes the contact of the probe sensor 5.
  • FIG. 4 only the selector lever 2 is tilted and the pushbutton 3 is shown pressed down, although in practice the simultaneous activation is unlikely.
  • Figures 1 to 5 show only one possible embodiment of the invention.
  • the selector lever 3 for example, by another lane or by other selector lever
  • all driving levels P, R, N, D are selected while another actuator or even more actuators (such as the button) is not necessarily for the operation of the Gear must serve.
  • the individual actuators can be locked or released in a corresponding grouping simultaneously.
  • all speed steps can also be selected by several buttons (one button each for P, R, N and D) that are disabled or released under certain conditions.
